SIDE BEARING.

Specification of Letters Patent.

Patented Jan. 16, 191%.

Application filed October 7, 1915. Serial No. 54,511.

To all whom it may concern.-

Be it known that we, FRANKLIN L. BAR- and EDWIN W. WEBB, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Side Bearings; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates particularly to side bearings for cars and is in the nature of an improvement on the side bearing for railway cars disclosed and claimed in Letters Patent No. 1,007,768, granted to John C. Barber, of date November 7th, 1914:.

Generally stated, the invention consists of -the novel devices and combinations of devices hereinafter described and defined in the claims.

In the said prior Barber patent, there was a novel arrangement for holding the axle of the bearing in position, but no means was provided for preventing rotation of the said axle.

The present invention provides a simple and eflicient means for holding the axle against rotation.

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a side elevation of the improved side bearing, some parts being broken away; and Fig. 2 is a vertical section taken on the line 00 00 of Fig. 1.

The improved device includes a roller supporting bearing or box 1, preferably of cast steel or malleable iron. The sides and base of this box are flanged and ribbed for greater strength and elasticity, and the side flanges are formed with axially alined pairs of inner and outer hubs or sleeve-like axle seats 2 and 3, in which are seated heavy axles 4L, upon which heavy bearing rollers 5 are loosely journaled. In the drawings, only one roller and one axle are shown, but a greater number may be employed. The

roller is located between the sleeves 2 and 3 and is held against axial movements thereby. The sleeve 2 has a round seat that quite closely fits the end of the axle, and it is formed with an integral web 6 that extends on the chord of an arc of the outer portion of the axle seat and engages a correspondingly shaped notch 7 in the end of the said axle. Thus the said axle is positively held against rotation.

The sleeve 3 is vertically elongated so that, when the axleis in position, a lock pin or rivet 8 may be passed through horizontal perforations that transversely intersect the upper portion of the said elongated seat. The ends of the lock pin or rivet 8 are preferably riveted against fiat lug surfaces 9 formed on the top of the said hub 3. Furthermore, said sleeve 3 has an integral stop flange 10 that is outwardly offset from the adjacent end of the axle 4 but extends above the lower portion of the said axle, when the latter is locked down by the rivet or pin 8. This stop flange 10 holds the axle against endwise movement in one direction, and the lock flange 6, in addition to the function already described, holds the said axle against endwise movement in the opposite direction.

IVhen the pin or rivet 8 is removed, or before it has been applied, the adjacent end of the axle 4 may be raised above the stop flange or lug 10, and hence, moved endwise through'the hub 3, for the purpose of inserting the same in working position, or removing the same therefrom.

The construction described, is very simple and at the same time, strong and durable.

What we claim is:

In a bearing of the kind described, the combination with a base flange having laterally spaced inner and outer hubs with axially alined axle seats, the outer of which seats is elongated, of an axle insertible into said seats by endwise movement through the elongated axle seat and having a notch in its inner end, a stop flange on the inner hub with which said notch interlocks to hold the axle against rotation and endwise movement in one direction, a stop flange outward of the outer end of the axle, said two stop flanges axle against endWise displacement, and a being located at diametrically opposite points, a pin passed through the elongated axle seat and cooperating With the stop flange on the outer hub to normally hold the In testimony whereof We aflix our signatures in presence of tWo Witnesses.
